激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

Which geometry, dopant and doping concentration on the achieve medium are most beneficial rely upon quite a few elements. The out there pump source (form of laser diode or lamp) and also the envisaged pumping arrangement are important things, but the material alone also has some affect. For instance, titanium–sapphire lasers have to be pumped with high intensities, for which the shape of the transversely cooled rod, operated with fairly small pump and laser beam diameter, is much more suitable than e.

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

Obviously, it is extremely desirable that a specified crystal high-quality is generated continually, Despite the fact that distinct laser designs might have a special sensitivity to product parameters.

亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。

Several laser crystal resources are actually demonstrated in which some saturable absorber content is included for passive Q switching of a laser.

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

It is apparent that various applications lead to very different specifications on laser acquire media. Because of this, a wide array of different crystals are utilized, and making the ideal choice is important for constructing lasers with the best possible effectiveness.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

In 2017, we made the globe’s largest Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals click here with exceptionally extensive emission spectra drives the event of laser diode pumped ultrafast solid-condition lasers. With the increase in pulse Electricity, peak energy, and repetition charge of stable-point out lasers, laser crystals will establish towards greater dimensions, higher crystal high quality, and controllable crucial functionality.

There is certainly a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline buildings. Some vital teams of crystals are:

人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
